TRB Tax Pro

A CA-grade Income Tax calculation engine for India (FY 2025-26) with AIS reconciliation and support for the Income Tax Act, 2025.

Built for precision, notice remediation, ITR-U compliance, and the 2026 Assessment transitions.

Features

• Marginal Relief (Surcharges): Mathematically rigorous computation across multiple thresholds (₹50L, ₹1Cr, ₹2Cr, and ₹5Cr).
• Section 87A Marginal Rebate: Precise resolution for the "Cliffs" under the New Regime (specifically mapping the ₹12 Lakh threshold gracefully).
• Multi-Year Support: Readily deploy algorithms for classical FY terminology or incoming Tax Year (TY) structures.
• Presumptive Taxation Validation (44AD/44ADA): Dynamic tests against digital transaction limits to unlock enhanced turnover rules (e.g. 5% Cash rules mapping to ₹3Cr limits).
• Automated AIS Reconciliation: Pull SFT entries, Salary, and Capital Gains directly from official JSON specs reducing manual mapping and notice exposure.
